Received a "fine" for £90 from parking eye despite paying correct amount for ticket and emailing them the same day to say their machines not working and wouldn't let me put registration number in correctly. Looked on Internet and lots of people seem in the same boat to and are being threatened with bailiffs etc if they don't pay fine yet the machines seem to be regularly out of use. Having to spend time and effort appealing but luckily have kept ticket and copy of email. Will never use their car parks again
